------------------------------------------------- Animal nutrition Introduction to animal nutrition There are seven major classes of nutrients: carbohydrates‚ fats‚ fiber‚ minerals‚ protein‚ vitamin‚ and water. These nutrient classes can be categorized as either macronutrients (needed in relatively large amounts) or micronutrients (needed in smaller quantities). The macronutrients are carbohydrates‚ fats‚ fiber‚ proteins‚ and water. The micronutrients are minerals and vitamins. The macronutrients

The metabolism of fats in the absence of glucose produces ketones that alter the blood pH‚ making it more acidic. This is a serious‚ acute condition (ketoacidosis) and if left untreated can cause death. Hyperglycaemia surfaces with increased gluconeogenesis‚ (the process in which glucose is produced preventing the body developing hypoglycaemia) and increased glycogenolysis. (the break down of glycogen which helps to regulate blood glucose levels) (Kitabchi et al

Homeostasis by definition is the technical term for the process of maintaining a constant internal environment despite changes in the external environment. The internal environment comprises of blood‚ tissue fluid‚ body cell contents and all metabolic processes taking place inside the body. This process is essential to the survival of a person and to our species as a whole. The liver‚ the kidneys‚ and the brain (hypothalamus‚ the autonomic nervous system and the endocrine system) help maintain

Diabetes mellitus is a group of metabolic diseases in which the individual has high blood glucose levels as a result of the inability of the pancreas to produce insulin‚ or as a result of the cells in the body not responding to the insulin produced. The aim of this documentation is to outline the normal regulation of blood glucose levels in the body which includes the role of the hormone producing alpha cells and beta cells in regulating these levels‚ and the effect that the pathophysiology of diabetes

Describe the role of the citric acid cycle as a central metabolic mechanism. Explain what happens to the cells’ abilities to oxidize acetyl CoA when intermediates of the cycle are drained off for amino acid biosynthesis. Glucose is a source of energy that is metabolized into glycolysis to pyruvate yielding ATP. To become more efficient‚ pyruvate must be oxidized into carbon dioxide and water. This combustion of carbon dioxide and water to generate ATP is called cellular respiration (Tymoczko‚
